3.2-4d=2.3d+3 i need the answer

borishaifa [10]

Answer:

d=0.031746

Step-by-step explanation:

1. Add 4d to both sides: 3.2=2.3d+3+4d

2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3

3. Subtract 3 from both sides: 3.2-3=6.3d

4. Simplify 3.2-3 to 0.2: 0.2-6.3d

5. Divide both sides by 6.3: 0.2/6.3=d

6. Simplify 0.2/6.3 to 0.031746: 0.031746=d

7. Switch sides: d=0.031746

Hope this helped!

Troy had 44 celery sticks on a tray for his party. He put peanut butter on 25% of the celery sticks. How many celery sticks on t

GarryVolchara [31]

Hello!

We know that any given percentage can be expressed as a fraction with a denominator of 100, as follows:

$\frac{x}{100}$

Because we want to find 25% of the celery sticks, we can convert this percentage into the following fraction:

$\frac{25}{100}$ = $\frac{1}{4}$

Now multiply this reduced fraction by the number of celery sticks:

44 × $\frac{1}{4}$ = $\frac{44}{4}$

The fraction $\frac{44}{4}$ can be reduced to a value of 11. We have now proven that 11 celery sticks received peanut butter.

I hope this helps!

Alex Ar [27]

Answer:

309

Step-by-step explanation:

a = 3, d = 6, n 52

Nth term of an Arithmetic sequence is given as:

$t_n=a +(n-1)d \\ \therefore \: t_{52}=3 +(52-1) \times 6 \\ \therefore \: t_{52}=3 +51\times 6 \\ \therefore \: t_{52}=3 +306 \\ \huge \red{ \boxed{\therefore \: t_{52}=309 }}\\$
